lsPEcIFIcAT-IONrenting par: of Letters Patent No. 730,228, dated June e, 190s. Application filed August 22, 1902. Serial Nd 120,662. (No model) .To all whom it may concern.-

Be it known that I, AMES G. BUMP, a citizen of the United States,'residing at Brad, in the county of Palo Pinto and State of Texas, have invented a new and useful-Excavating Apparatus, of which thefollowing is a specification. j

My invention relatesto an improved excavating apparatus adapted for use in cleaning out tanks, for excavating cellars, for dredging streams, and for other similarfpurposes; and it consists in the peculiar' construction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, VFigure 1 represents a side elevation of Van excavatingapparatus embodying my improvements. Fig. 2 represents adetail top plan view4 ofa portion thereof, showing the revoluble mast and the devices carriedithereby. Fig. 3 represents a detail sectionalY view showing the revoluble mast or perpendicular shaft and the drums and arms mountedjthereon. Fig. 4 represents a section taken on line 44 of` Figzl, showing the mechanism for revolving themast in elevation. Fig. 5 represents a section taken on line 5 5 of Fig. 3, showing the mechanism for communicating motion from the mast tothe drums.

The same reference-numerals indicate corresponding partsinall the vligures.

In the embodimentof my inventionl provide a suitable supporting-'truck 1, on which is stepped the lower end of a 'revoluble mast or shaft 2, which is adaptedtobe supported in an upright or inclined position and 'to' be revolved on the truck which forms` its sup- At the Vupper end of the mast is a spindle 3, whichitur'nsin acap 4. Disposed radiallywith reference to the' truck or supporting-base, atjsuitable distances therefrom, are a series,v here shown as four, of anchoring devices 5, each of which includes a winch 6.` Guys 7 ,havetheirfupper endsV attached`to the cap 4, and the lower portions ofi the saidguysare attached' to and lcoiled upon the -winchesdv The said-'guysserveto s upport the'ma'st, as will be understood:

The mast 2 comprises the upper section S and the lower section 9, which are pivotally jointed together, as at 10, whereby the upper j wheel while-the other 'ge'ar 'is' engaged" l1 'with', so yt-hat-onlyo'ne ofthe reversing `ears section may be ,folded downwardly or extendedv from and in line with the lower sece tion. A lock-band 11 isplaced on the mast and is adapted, when the sections thereof are disposed in liliewith each other, to bemoved to a position surrounding the pivotal joint 1() to securethe said sections rigidly together. lPrior to yturning the upper sectionon .the

pivot S to fold the mast the ,lock-band must be moved from the joint-'10,.as will befunderstood. 'The mast is provided-in onerside'with a series of teeth or stops 1-2, .which extend from the pivotal joint nearly tothe upper .end ofthemast.

t I will now describe means whereby themast may be revolvedin either qdirectionzw'ithout reversing the direction of ethe horse orteam employed to revolve said mast.

The horizontally-disposed master-wheel 13 revolves on the lower section of the mast and is provided with internal spurs 14. A sweeplever 15, to which the horse or team .is attached, is secured tothe master-wheel and employed to rotate said wheel. A spur-pinion 16 is fixed tothe mast 2 and revolves therewith. A 'pair of reversing-pinions 17 and 18 are provided withgrel'atively iixedbearings 19 and 20, respectively,.by meansof which they are attacheditofa'reversing-lever 21. The said rei versing-,pinions are adapted to engage the internal gear -1-4 of the master-wheel at different points thereon. The reversing-lever 21 is fulcrumed to the mast 2 at 21' and is so disposed as to bemoved on its fulcrnm to disengage one of the reversing-gears from the-masteris at any time in engagement with the masterwheel and so that either of the reversing-gears may be engaged with the master-wheel at will by raising or lowering the free end of the lever, as desired. The reversing-gear 18 is adapted to engage the pinion 16 and communicate motion therefrom to the master-wheel. The said ypinion 16, fixed to the mast 2,is;also.en'gaged Iby an idler 22,

which hasj a .relatively fixed bearing and which is adapted tojmesh'withthe reversing-gear 17 when thelatterj-is .engaged with the master-wheel, thereby communicating motion to 'said wheel and cause it` to revolve in the opposite direction.

too

It will be understood from the foregoing that by properly operating the lever 21 the shaft or mast 2 may be caused to revolve, either in the same direction with the master -wheel and sweep-lever or reversely with reference thereto. This enables the horse or team to be continuously driven in one direction when the apparatus is in operation and obviates the necessity of reversing the horse or team when it is desired or becomes necessary to reverse the rotation of the mast.

A pair of rotatable drums 23 and 2 are loosely mounted on the mast 2 and are adapted to slide verticallythereon, one of said drums being mounted above the other. The drum 23 is provided with a dog 25, which engages a ratchet-wheel 2,that is slidable on and revoluble with the mast 2, said. mast having a longitudinally-disposed feather 2 formed thereon, which is engaged by the ratchet-wheel and which serves to lock said wheel against rotation independently of the shaft or mast while permitting it to slide vertically thereon. The drum 2l is provided with a dog 27, which engages aratchet-wheel 2S, mounted on the mast in a manner similar to the wheel 26. The wheel 2S is so disposed on the mast that the teeth thereof are reversed with reference to those of the wheel 2G. I'Ience motion will be imparted to one ot' the drums, and it will be caused to revolve with the mast when the latter is revolved in either direction.

A pair ot' arms 29 and 30 are carried bythe shaft or mast 2 and are adapted to be swung laterally thereon, so that the arms may be disposed at any desired angle with reference to each other, and the said arms are also adapted to be turned to any desired inclination. Each of the said arms is provided at its outer end with a winch 3l, on which is partly coiled a rope 32, that is attached to the mast-head. This enables the arms to be disposed at the desired inclination and also enables them to be moved vertically on the mast with the drums 23 and 24E, I provide a winch 33, which is here shown as attached to thc band or collar at the heel of the arm 30 and on which is partly coiled the opposite ends of a rope 3l, that passes over a pulley 3l', attached to the head of the mast. By means of this winch the drums, arms, and ratchet-wheels may be raised or lowered on the mast simultaneously to adjust them to any desired height above the ground. The arms 20 and 30 are provided with suitable guys to maintain them at the appropriate angular adjustment with reference to each other, so that their outer ends may be disposed at any desired distance apart. Each of said arms is hollow or slotted throughout its length and is provided with a roller 35, which is adjustable longitudinally in said arm. T he outer end of each arm is bifurcated and the members thereof flared outwardly and between which a-pulley 3U is mounted and connected thereto by a swivel Each of the arms 29 and 30 is provided with a trip 3S te automatically dump the Scrapers when the latter are elevated to the outer ends ot' the arms.

On a support or base 259, which is adapted to be placed at a suitable distance from the truck and on the opposite s-ide of the tank or other place where the excavation is to be made therefrom, stepped the lower end of a shaft 40. The said shaft is maintained in an upright position by guys il and anchors 4t2, the guys being attached to a cap 43, in which the upper end of the shaft 40 has its bearing. Ou the said shaft are a pair of drums 44 45, one above the other, and the said drums are connected to the said shalit by dogs and ratchet-wheels 4 -6 4-7, which. are similar to those used to secure the drums 23 2i on the mast 2. A pair of arms i8 4S), which are similar to the arms 2) 30, hereinbefore described, are pivotally mounted on the shaft et() and are provided with appropriate guys 50 to dispose them at any desired angle apart. A cable 5l connects the drums et together and has its ends revcrsely coiled thereon. Said cable engages the rollers carried by the arms 30 and 40 and also engages the pulley carried bythe arm30. A similar cable connects the drums 2l 45 together, as shown. To each of the cables :is attached a dump-scraper 52.

It will be understood that when the apparatus is in operation the Idump-Scrapers will be simultaneously carried by the cables, so that the loaded scraper will approach the mast 2, while the unloaded scraperwill be returned toward the shaft ai). This is accomplished without reversing the team or horse and by properly manipulating the shiftinglever 2l. Hence my improved excavating apparatus is adapted to perform its work very expeditiously, as one of the scrapers is almost constantly engaged in carrying earth. The provision of the pawl-and-ratchet con nections between the drums and the shaft-s enables the cables to be lengthened out or shortened between the two masts, according to the distance between them.

A dog or key 54 coacts with the teeth or stops in one side of the mast 2 to support the drums 23 24E and the arms justed.

By widening the angles between the arms which form the guides for the cables as the work progresses, which may be done by means of the guys provided for the arms, an area of considerable width may be excavated before it is necessary to shift the position of the apparatus. l
